A survey of aircraft engine health monitoring systems

TLDR

Research and monitoring applications for other engine types provide a foundation for exploring aircraft engine health monitoring systems. The survey aims to review commercial aircraft engine health monitoring systems, identify shortcomings in current practice, and lay groundwork for future research at NASA Ames. The authors conduct a survey of existing practice and research, first examining current systems to pinpoint gaps, then reviewing alternative approaches to address those gaps.

Abstract

This paper presents a survey of engine health monitoring systems for commercial aircraft. The state of practice is explored first, with the purpose of identifying the shortcomings of current systems. The state of the research to address these shortcomings is them surveyed to explore the alternatives. Research and monitoring applications for various other types of engines provide a good basis for further exploring the topic. This survey is meant to serve as a precursor to engine health and monitoring research at the NASA Ames Research Center.
